Fugro, Ikon team on drilling geohazard prediction

Site survey expertise combines with seismically-derived geopressure analysis.

Fugro Geoconsulting and Ikon Science are teaming on a wellsite geohazard prediction service that combines Fugro’s expertise in site survey with Ikon’s seismically-derived geopressure analysis. Geohazards such as shallow gas pockets are a danger to drillers around the world. While they can be identified from seismic amplitude data, their evaluation is frequently compromised by a lack of log data.

The new service leverages Ikon’s quantitative geopressure analytics alongside integrated workflows from Fugro’s geoscientists, including reconciliation of petrophysically-interpreted logs with seismic amplitudes and pressure interpretation. These are used to produce a ‘continuous unbroken set of pressure profiles from the sea bed to total depth.’ The combined approach to pre-drilling wellsite analysis is claimed to provide a more complete and accurate evaluation of pore pressure in the shallow section. Feedback of Ikon’s findings to Fugro will allow refinement and enhancement of the geohazard interpretation and aid in the identification of shallow faults that could cause dangerous overpressured sands.
